MACHINE FOR MAKING HORSESI-IOES.

Specification of Letters Patent.

Patented Dec. 7, 1909.

To all whom 'it may concern:

Be it known that I, RUFUS S. MATTEsoN, a citizen of the United States,residing at the city of Providence, in the county of Providence andState of Rhode Island, have invented certain newY and usefulImprovements in Machines for Making Horseshoes,

of which the following is a specification,.ref

erence being had therein to the accompanying drawing.

This invention relates to the manufacture of horse shoes and has for itsobject to provide a machine to which bars of iron the length of ahorse-shoeare fed, these bars being acted upon and formed with thenecessary grooves and bevels, also with the nail holes made therein,then automatically bent into the desired form and dropped out acompleted shoe.

With these objects in View the invention consists of certain novelfeatures of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying` drawings: Figure l-is a plan View of my improvedmachine. Fig. 2-1s a sectional elevation through the machine on the linetraversed by the shoe blank, showing the two sets of rotatable dies andthe feed rolls by means of which the shoe blanks are fed through themachine and carried to the bending mechanism at the left. Fig.3illustrates a section on line 3 3 of Fig. 2 through one of the dies andits supporting plate. Fig. iis a View showing the blank in position tobe bent by the forming block, which die is in its eXtreme rearwardposition. Fig. 5-illustrates the die block as being moved forwardforming the blank around the same, and in a position just before it hascompleted its forward stroke, the completed forward stroke beingillustrated in Fig. 1. Fig. 6-shows a cam actuated by the backwardmovement of the forming mechanism whereby the positioning plates aredrawn apart to receive the blank, which plates are automatically causedto engage the ends of said blank when released by said cam to hold thesame ina central position to be acted upon by the forming block. blank.Fig. S-is a sectional view on line 8 8 of Fig. 7. Fig. 9-is a viewshowing the edge of the first rotating die working in conjunction withthe lower backing roll to form the horse-shoe blank. Fig. lO-is the Fig.7-shows the shoeV second rotating die which finishes the beveling, therecesses and the holes in said blank.

Referring to the drawings, at 1 is the frame of the machine on which ismounted the operating mechanism. At 2 is the countershaft on which ismounted the driving pulley 3 and the pinion 11. This pinion meshes withthe large driving gear 5 which is mounted on the shaft 6. Also mountedon this latter shaft is the rotatable die block 7 which roughs out ormakes the first impressions on the shoe blank. At 8 is a backing rollgeared to run in time with the die roll shaft and arranged to receivethe pressure of the die block as the same is making its impressions inthe blank, and also beveling or shaping a shoe at the underside into thedesired form. A second or finishing die block 9 is mounted on the shaft10 which is driven in time with the first die block through the gearsl1, 12 and 13. This second die block also has a backing roll 9a drivenin time with it. The upper feed roll 14 is driven through the sprocketchain 12a from shaft 6 and is arranged to engage the blank and carry itfrom one die block to the other along the guide trough 53. The feedrolls 15 and 16 receive the blank from the second die and deposit it inposition to be engaged and bent into the desired form. rlhese latterrolls are driven through the sprockets 28, 29, 30 and 31, and thesprocket chains 32 and 33.

The first die block 7 is designed to bevel the blank slightly at 17, inthe manner best illustrated in Fig. 9, forming two grooves orimpressions 18-19, see Fig. 7, by the raised portions 20 and 21 on theface of the same. Each die block is preferably made separate from itsbearing member 22 and is secured to the sameby means of the setscrews23-23 through the ears 2li-*24. The second die block 9 is similar to thefirst block 7, the only difference being that the beveled portion ismade a little deeper as at 25, see '.Fi'g. 10, and the pins 27 are alittle longer so that the holes 26 may be punched entirely through theblank for the reception of the nails.

At 55, see Fig. 2, is a sliding gage which may be drawn out and set toreceive blanks "of dierent lengths. At 56 is a stop lever with acounterweight 5S whereby-said end is normally held up in its engagingposition. At 59 is a cam located on the periphery of the circular plate60 which carries the second die. As this plate revolves the cam comes incontact with the lever 56 pressing the same downward and allowing theblank to be carried forward by the action of the feed rolls intoengagement with the second die block 9.

In the bending portion of the machine the centering plates 34 34 areadapted to slide toward and from the center, the outer ends of theseplates being engaged by the connections 35-35, see Fig. 2, the lower'ends of which connections are fixed to the shafts 86-36, see Fig. 4.Also fixed to these shafts 36 are the arms 37-37 which are pivotedtogether at their inner ends, and a cam portion 38, for engaging saidarms, see Fig. 6 is carried by the bar 39.

Then the shoe blank 40 is fed to the bending device the form block 41 iswithdrawn into the position illustrated in Fig. 4. At the rear end ofthe stroke of this form block t-he cam 38 is caused to engage the armsdT-37 to raise them substantially into the position illustrated indotted lines in Fig. 2, thereby rotating the shafts 36 and drawing apartthe centering plates 34-34 preparatory to receiving a shoe blank. Afterthese plates have been drawn apart a shoe blank is deposited by the feedrolls into the position illustrated in Fig. 4, then as the form blockstarts to move ahead, and before it engages the blank, the cam 38 iswithdrawn from the arms 8T allowing them to drop of their own weightassisted by the tension of the spring 42, thereby carrying the centeringplates inward engaging the blank and moving it to the exact centralposition where it is directly engaged by the forwardlymoving form blockand carried through the opening between the plates 423-43 and bent intothe form illustrated in Fig. 5. Just before the termination of thisforward stroke the cam portions 44-44 engage the rolls 45-45, which aremounted on the pivoted levers 46-46, carrying these ends outward and atthe same time carrying the opposite ends 47-47 inward to press the endsof the shoe blank tightly around its form block, thus completing theformation of the shoe. The form block is then withdrawn carrying theshoe with it over the opening 4S through the bed where the shoe isdropped off completed. The reciprocating motion is given to this formblock from the shaft l0 through the beveled gears 49, shaft 50, crank 5land connection 52.

The operation of the invention may be more fully described as follows:rIhe machine may be driven continuously from any desired source of powerthrough a belt, not shown, and the pulley 3, the rolls all beingsuitably geared together to run in time with each other. Short bars ofiron of the desired size and length after being heated, are placed oneat a time into the guide trough one end resting against the adjustablesliding gage 55, said gage having been previously set to receive therequired length of blank and hold it in position to be engaged at theproper time by the first die. As this die block revolves it comes inContact with the blank and operates upon it at the same time carrying itforward until its front end is forced between the feed rolls 14-14 whichcontinue to move the same toward the second die until its forward endbrings up against the stop 56. .lVhile the bar is in engagement withthis stop the feed rolls continue to revolve and slip on said blankuntil the cam portion 59 presses down said lever and releases the blankthereby allowing` it to pass forward at the proper time to be acted uponby the second dies. It will be seen that by the action of this stoplever the second dies are always bound to engage the blank at exactlythe right time regardless of the length of the blank.

By this construction it will be seen that blanks of any desired lengthmay be passed through the machine and be autonlatically taken care ofand not allowed to enter the second die until the same is in a positionto receive them. By this arrangement the second die will always registerperfectly on the work with the first die, which latter die finishes theblank by completing its shape and punching the nail holes through thesame, after which said blank is carried forward by the other feed rollsand deposited into the bending machine where it is formed into the shapeof the horseshoe, and then automatically deposited in a suitablereceptacle in a finished condition.

The machine is practical in its construction and will form horseshoesrapidly and finish the same without the aid of skilled labor.

I-Iaving thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a machine for making horseshoes the combination of a rotatableroughing die, a rotatable finishing die, means for rotating said dies inunison, means located between said dies for feeding the blank from theroughing die to the finishing die, and automatically operated meanslocated between said feeding means and said finishing die for positivelyengaging said blank to arrest the feeding movement thereof, and meansactuated by the finishing die when the latter reaches an operativeposition to withdraw said arresting means, whereby said finishing diewill register with the impression made by the roughing die.

2. In a machine for making horseshoes,

Mast/o the combination of a rotatable roughing die, a rotatablefinishing die, means for rotating said dies in unison, means for feedinga blank from the roughing die to the finishing die, a withdrawable stoparranged to interrupt the passage of the blank between the feeding meansand said finishing die, said feeding means being constructed to permitof such interruption, and means operated by said finishing die forwithdrawing said stop, said withdrawing means being timed to cooperatewith said nishing die, whereby the latter will register with theimpression made by the roughing die. v

3. In a machine for making horseshoes, the combination of a rotatableroughing die, a rotatable finishing die, means for rotating said dies inunison, means for feeding a blank from the roughing die tothe finishingdie, a pivoted finger arranged to normally interrupt the passage of theblank between the dies, said feeding means being constructed to permitof such interruption, and a cam carried by the finishing die forautomatically rocking said finger to withdraw the same.

4. In a machine for making horseshoes, the combination of a rotatableroughing die, a rotatable finishing die, means for rotating said dies inunison, means for feeding a blank from the roughing die to the finishingdie, a stop provided with a counterbalanced portion and arranged tointercept the path of movement of the blank between the dies, and meanscarried by said finishing die for automatically withdrawing said stop.

In testimony whereof I affix my signature in presence of two witnesses.
